面向对象电网知识库系统的研究与实践

OBJECT-ORIENTED POWER SYSTEM KNOWLEDGE BASE SYSTEM AND ITS APPLICATION

把关系型电网数据库内容作为事实知识的主体 ,并抽象为知识对象的属性 ,数据间的联系以及由数据到图形的规则抽象为知识对象的描述与过程 ,再把具有相同结构、属性和功能的知识对象抽象为知识类 ,并通过继承与组合获得具有较小知识冗余的层次型知识类库 ,由此构造的面向对象的电网知识库系统 ,可以成功地解决在电网图上直接管理和维护电网数据库以及集结分散在电网数据库中的结构类数据自动生成规范电网图的双向问题。

Structure of Object oriented Power System Knowledge Base System is proposed. Facts Base is implemented by Power System Relation Database(PSRDB)and Knowledge Class Library is implemented by technology of Microsoft Fundamental Class. The knowledge objects corresponding with power equipment are the encapsulation of the properties that are the facts described by data in PSRDB and the processes that are rules to manage PSRDB and to create power system figures. And then this paper succeeds in solving the two way problem,one is to safeguard the PSRDB from the power system figure directly and the other is to create the power system figure from PSRDB automatically.
